A volcanic neck forms when magma solidifies in the vent of a volcano, after the solidification the volcano goes either dormant for an extended period of time or goes extinct. During this period of quiescence the ash around the vent erodes away as well as all the other light material leaving only the spine that was the plug in the vent. This will last the longest as it is very densely solidified magma versus a loose conglomerate of ash on the flanks of the volcano.
No. A vent is the part of the volcano from which material erupts. One volcano can have multiple vents.
If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly
vent
When the lava stops erupting from the central vent, a volcanic cone or crater may form at the top of the volcano. This is created by the accumulation of solidified lava, ash, and other volcanic materials around the vent opening. The shape and size of the cone can vary depending on the type of eruption and the characteristics of the volcano.

The general term for the different types of material that a volcano spews out is ejecta.

If the volcano is active, there may be vents around the volcano as well as on top. A vent is where volcanic material (lava, steam, ash) is being released.
